TRACK-RAIL.

Application filed December 24, 1915. Serial N 0. 68,572.

To all whom z'twihay concern:

Be it known that we, JOHN F. LEWIS and J OHN LLOYD, both citizens of theUnited States, and residing at North Braddock, in the county ofAllegheny and State of Pennsylvania, have invented certain new anduse:ful Improvements in T rack-Balls, of which the following is aspecification.

Our invention relates to the construction of the rails forming thetracks of steam, electric and like railways; and the invention, which isapplicable to the T-rails usually employed on steam railroad systems andthe rails and the flanges on the wheels of the.

cars, locomotives, and other rolling stock is lessened, wear on the railheads is very materially reduced, and liability of derailment on curvedtracks of the railwayis avoided and overcome. V

Another object of the invention is to provide 'a track rail having novelmeans for supplying and maintaining a supply of lubricant for the wheelflanges of the rolling stock. g

A further object of the invention is the provision of a track railhaving the novel construction and arrangements of parts shown in thedrawings, and covered by the claims, and more fully describedhereinafter.

Referring now to the drawings, forming elevation of a rail of the T-headtype, the rail head being partly broken away to show one form oflubricant retaining pocket or recess of rails made in accordance withour invention. Fig. 2 is a side elevation showing a portion of thelength of the rail of Fig. 1. Fig. 3 is an end elevation of a guardrail, of the girder type, used on street railways, having lubricantholding pockets 1n the side surfaces of the head and guard flange, therail being partly in section to show the construction of a modified formof lubricant pocket or recess. Fig. 4 is aside elevation of a portion ofthe length of the rail of Fig. 3, the guard flange being partlySpecification of Letters Patent.

broken away to show the relative arrangement of the multiplicity ofpockets. Fig. 5 is an end elevation of the head portion of a girderguard rail, partly in section, to show a modified form of lubricantholding pocket. Fig. 6 is a side elevation,'with the guard flange partlybroken away, of a part of the length of the rail of Fig. 5. Fig. 7 is anend elevation, similar to Fig. 1, and Fig. 8 is a side elevation likeFig. 2, showing another modification in the shape of the lubricant aretaining pockets in rails constructed in accordance with our invention.Fig. 9 is an end elevation, and Fig. 10 is a side elevation similar toFigs. 1 and 2, showing another form of lubricant holding pocket. Fig. 111s an end elevation, and Fig. 12 is a side elevation similar to Figs. 1and 2, showing still another form of lubricant holding pocket or recess.Fig. 18 is an end elevation, and Fig. 14 is a side elevation, like thatof Figs. 1 and 2, showinga still further modification in theconstruction of the lubricant containing pocket of rails made inaccordance with our invention.

In the accompanying drawings the numeral 2 designates the head of therails which is joined integrally by the web 3 to the base flange 4 ofthe rails.

,In the construction shown in Figs. 1 and 2, the side surface 25 of therail head 2 is provided with a series of recesses or indentations 26which are rectangular in outline andwhich are arranged in rows, with therows of depressions in staggered relation. The recesses preferably areformed in the rail rolling operations, in such case suitably shapedprojections being provided on the roll surfaces to form the recesses orindentations on the side of the rail head during the rail rollingoperations. However, when de s red or found necessary, the recesses maybe formed .by milling, by drilling, or in any other desired manner,after the rails have been rolled, and even after the rails have beenplaced in position on the road bed of g a railway track.

In the construction shown in Figs. 3 and 1 4, the side surface 45 of therail head 2 is provided with a multiplicity of staggered recesses 46which are cylindrical in outline,

and one side surface 47 of the guard flange 5 of this rail, which is ofthe girder type used in street railway constructions, is provided with asimilar series of recesses 46.

' In the construction shown in Figs. 5 and 6, the side surface 65 of therail head 2 is provided with a series of narrow recesses 66 arranged toextend lengthwise vertically. As the rail of Figs. 3 and 4 is of theguard rail girder type, the side surface of the guard flange 5 is alsoprovided with a series of recesses 66 similar to those in the side 65 ofthe rail head.

In the construction shown by Figs. 7 and 8, the sidesurface 85 of therail head 2 is provided with a zigzag groove or recess 86 which extendsfrom one end to theother of the rail or which'mav extend only throughsuch portions of the length of the rail as is deemed necessary ordesirable. \Vhen desired, the recess 86 may be straight instead of, asis shown in these figures, being made zigzag, in form.

In the construction shown in Figs. 9 and 10, the side surface 105 of therail head 2 is provided with a series of spaced recesses 106 which arecylindrical in outline.

In the construction of Figs. 11 and 12, the side surface 125 of the railhead 2 is provided with a series of narrow recesses 126 arranged toextend lengthwise vertically at separated points in the length of therail.

In the construction shown in Figs. 13 and 14, the side surface 145 ofthe rail head 2 is provided with a series of narrow recesses I 146 whichextend lengthwise at an angle to the horizontal.

After the rails having the recesses or indentations in the side surfacesof the rail heads 2 are placed in position in a railway t ack, thepockets forming the recesses are filled with a viscous lubricant such asgrease or tallow. or thev may be filled with lead or other soft metal,graphite or other semifiuid lubricant or lubricating compound.

The side surface of the rail having the pockets. being on the side ofthe rail. engagmg with the wheel flanges of rolling stock hauled on thetrack, will be smeared with lubricant from the pockets, and in this waywill greatly lessen the friction between the rails and the wheel flangesof the rollin stock. When found necessary or desirable, the pocketsformed by the recesses in the side surfaces of the rail heads 2 arefilled with waste, felt, or similar absorbent material, and the waste isimpregnated or saturated with oil or other. liquid lubricant. In suchcase the waste within the pocketswill absorb the liquid lubricant andmaintain a sup- 1 ply of lubricant for an indefinite time in position tobe transferred to the passing wheel flanges and be transferred by thewheel flanges to the side surfaces of the raitheads coming in contactwith the wheel flanges.

The advantages of our invention, which the art, arise from the provisionand mainwill be clearly apparent to those skilled in\ tenance of asupply of lubricant, in position to come into contact with the wheelflanges of rolling stock hauled over the rails, and in position to betransferred through the medium of wheel flanges to the side surfaces ofthe rails engaged by the'wheel flanges. In this way the enormousfriction between the wheel/flanges and rail heads, especially onthec'urved tracks of railways, is greatly lessened and the extremelyrapid wear on theside surfaces of the rail heads on curved tracks ismaterially reduced.

Modifications in the construction and arrangement, and the location ofthe lubricant containing pockets, may be made without departing from ourinvention as defined inthe appended claims.

We claim 1. A railway track rail having a car wheel supporting head,with at least one side of said head having a recess therein forming'alubricant receivingpocket, and said pocket being adapted to maintain asupply of lubricant in position to contact with and lubrihaving recessestherein and said recesses forming lubricant receiving pockets adapted tomaintain a supply of lubricant in position to contact with and lubricatethe flanges of car wheels traveling on said track rail.

In testimony whereof we have hereunto set our hands.

JOHN F. LEWIS. JOHN LLOYD.
